Brian, I think your example actually proves Roger's point.  
The .values's only apply to FN, not to N. I'm having trouble  
imagining a situation where you'd use the value-excerption on a  
structured element. It only seems to make sense on elements that only  
take a simple value.

If you'll think of the structure of a microformat as a tree, it's  
only the leaves that take value excerpting. This could be a bit  
challenging, because there are elements in hCard that can be either a  
leaf or have children (like AGENT and ATTENDEE). I'm sure we can  
figure out how to deal with these, though.

If you can develop specific cases, I'll add them to our test suite.
